Discussion
Tetraplodon urceolatus is an arctic or alpine moss very similar to reduced northern forms of T. mnioides; however, T. urceolatus has short yellowish setae, small strongly concave appressed leaves, and a short hypophysis about as long as the urn, sometimes lighter, and the same color or darker than the urn with age, and with relatively fewer stomata generally confined to the distal portion of the hypophysis. In general, T. urceolatus has firm leaves with stiff, rounded apices and thick distal cell walls. The exostome teeth of T. urceolatus are reflexed, orange-red at the apices, and inserted below the capsule mouth.
